[0001] 1. Field of the Invention

[0002] The present invention relates to a cosmetic brush assembly havinga brush used for the make-up of a cosmetic powder on the one end thereofand more particularly, to a cosmetic brush assembly capable of couplinga cosmetic powder retaining tank on the other end thereof and injectingcosmetic powder in the cosmetic powder retaining tank to the brush bythe action of air pumping, such that in use, the injection force of thecosmetic powder can be increased and an amount of cosmetic powderinjected can be adjusted.

[0003] 2. Description of the Related Art

[0004] In order for a user to paint a cosmetic powder retained in apowder case on his or her face, generally, she first opens the cover ofthe powder case and then covers the brush mounted on a cosmetic brushassembly with the cosmetic powder exposed to the outside. After thecompletion of the make-up, however, she frequently fails to keep herpowder case in a clean state due to the carelessness of the treatment.

[0005] Additionally, it is inconvenient to carry both the powder caseand the cosmetic brush assembly, respectively.

[0006] In a conventional cosmetic brush assembly, typically, the brushand the cosmetic powder tank are simply connected to each other, suchthat when the cosmetic powder is injected to the brush, the air pressureis dispersed and is thus difficult to reach the terminating end of thebrush. In addition, because of a simple configuration, an amount of thecosmetic powder injected cannot be appropriately adjusted. As a result,it has been found that the brush is not uniformly covered with thecosmetic powder. With the conventional cosmetic brush assembly,therefore, a user cannot achieve a desired painting.

SUMMARY OF THE INVENTION

[0007] It is, therefore, an object of the present invention to provide acosmetic brush assembly capable of having a cosmetic powder retainingtank on the one end thereof, whereby a cosmetic powder in the cosmeticpowder retaining tank is injected to a brush by air pumping.

[0008] It is another object of the present invention to provide acosmetic brush assembly capable of adjusting an amount of cosmeticpowder injected to a brush from the cosmetic powder retaining tank andinjecting the cosmetic powder to the whole brush in a uniform level.

[0009] It is yet another object of the present invention to provide acosmetic brush assembly capable of treating a cosmetic powder in an easymanner, thereby preventing the interior of a handbag from being stainedwith the cosmetic powder, while a powder case is kept in the handbag.

[0010] It is still another object of the present invention to provide acosmetic brush assembly capable of having a beautiful appearance andexerting various kinds of functions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0025] Now, an explanation of the configuration of a cosmetic brushassembly according to the present invention will be hereinafterdiscussed with reference to the accompanying drawings.

[0026]FIG. 1 is a perspective view of a cosmetic brush assemblyaccording to an embodiment of the present invention, FIG. 2 is anexploded perspective view of FIG. 1, and FIG. 3 is a sectional viewtaken along the line A-A in FIG. 1.

[0027] Referring to the drawings, a cosmetic brush assembly 10 accordingto the present invention includes a brush mounting member 20 having abrush 22 on the top end thereof. The brush mounting member 20 is asubstantially hollow cylinder and forms a screw or protrusion (orgroove) on the bottom end thereof, into which an adjusting part 50 aswill be hereinafter discussed for adjusting an amount of cosmetic powderinjected is screw-coupled or fitted. Also, an injection nozzle 40, whichfunctions to guide the cosmetic powder to the brush 22, is inserted intothe hollow portion of the brush mounting member 20, an explanation ofwhich will be below discussed.

[0028] The injection nozzle 40 serves to guide a flowing passage of thecosmetic powder supplied from a cosmetic powder retaining tank 30 andtakes a substantial cylinder. The injection nozzle 40 has a closed topend on which a plurality of injection holes of predetermined sizes andan opened bottom end. Also, the closed top end of the injection nozzle40 is placed on the interior of the brush 22, for directly injecting thecosmetic powder to the brush 22.

[0029] As mentioned above, the brush mounting member 20 is screw-coupledto the adjusting part 50 for adjusting an amount of cosmetic powderinjected to the brush 22, on the bottom end thereof. Also, the adjustingpart 50 is screw-coupled to the cosmetic powder retaining tank 30 aswill be discussed below.

[0030] In other words, the adjusting part 50 includes a hollow housing52 screw-coupled to the cosmetic powder retaining tank 30, a tubularbody 54 inserted into the hollow housing 52 under the support of anelastic body to close the hollow portion of the hollow housing 52, and apressure member 56 for applying a force to the tubular body 54 to openthe hollow portion of the hollowing housing 52.

[0031] The pressure member 56 of the adjusting part 50 is composed of asubstantially cylindrical member 56 a racing between the brush mountingmember 20 and the adjusting part 50 screw-coupled to each other and ahorizontal member 56 b screw-coupled on the inside of the cylindricalmember 56 a and horizontally moving in a length direction of thecosmetic brush assembly 10, particularly, in a length direction of thehollow portion of the brush mounting member 20, in accordance with theracing of the cylindrical member 56 a.

[0032] At this time, the horizontal member 56 b may be formed integrallywith the opened bottom end of the injection nozzle 40. And, graduationsfor measuring an amount of racing of the cylindrical member 56 a arearranged on the outside of the cylindrical member 56 a. Thus, the amountof racing of the cylindrical member 56 a can be checked by the eyes of auser, such that an amount of cosmetic powder injected from the cosmeticpowder retaining tank 30 can be adjusted. However, it can be appreciatedto those skilled in the art that means for measuring the amount ofracing of the cylindrical member 56 a is not limited to the graduations.

[0033] The cosmetic powder retaining tank 30 retains the cosmetic powdertherein and is provided with an air pumping part 32 for injecting thecosmetic powder to the brush 22, on the bottom end thereof.

[0034] Therefore, the cosmetic powder in the cosmetic powder retainingtank 30 is uniformly injected via the injection nozzle 40 to the brush22, as indicated by arrows in FIG. 5, by the air pressure flowing intothe cosmetic powder retaining tank 30 by the air pumping of the airpumping part 32. Then, the user of the cosmetic brush assembly 10 canpaint the cosmetic powder on his or her face in the same manner as aconventional practice.

[0035] Referring now to FIGS. 3 to 5, an explanation of an operationstate of the cosmetic powder brush assembly 10 according to anembodiment of the present invention will be discussed.

[0036] Referring to FIG. 3, first, the hollow housing 52 of theadjusting part 50 is screw-coupled between the cosmetic powder retainingtank 30 having the air pumping part 32 on the bottom end thereof and thebrush mounting member 20, and the injection nozzle 40 is inserted intothe hollow portion of the brush mounting member 20.

[0037] The tubular body 54 is inserted into the hollow housing 52 of theadjusting part 50 and attaches flanges 54 a and 54 b of predeterminedsizes on the both ends thereof. The flanges 54 a and 54 b function toprevent the tubular body 54 from being deviated from the hollow housing52, thereby making it possible to move the tubular body 54 in a lengthdirection thereof.

[0038] On the other hand, the tubular body 54 is provided with aplurality of substantially oval holes H in a length direction thereof onthe side adjacent to the bottom end thereof. The tubular body 54 has anopened top end on which the cut conical flange 54 b is attached.Therefore, the cosmetic powder in the cosmetic powder retaining tank 30flows into the plurality of holes H on the side of the tubular body 54and is thus injected through the opened top end of the tubular body 54,as indicated by arrows in FIG. 5.

[0039] Between the lower portion of the top end of the tubular body 54and the upper portion of the inside hollow portion of the hollow housing52 is provided an elastic body 58. By virtue of the elastic force of theelastic body 58 and the flange 54 a of the lower portion of the tubularbody 54, the tubular body 54 is kept completely exposed on the upperportion of the hollow housing 52. In this state, the holes H formed onthe side of the tubular body 54 are kept completely closed by the insideof the hollow housing 52.

[0040] As discussed above, in the state where the holes H on the side ofthe tubular body 54 are closed, if the cylindrical member 56 a of thepressure member 56 of the adjusting part 50 is raced, the horizontalmember 56 b screw-coupled to the inside of the cylindrical member 56 amoves horizontally along the direction of an arrow as indicated in FIG.4. In that case, as the horizontal member 56 b moves in a lengthdirection of the cosmetic brush assembly 10, the force in the arrowdirection of FIG. 4 is applied to the tubular body 54 of the adjustingpart 50, such that the tubular body 54, which is in contact with thehorizontal member 56 b, moves horizontally in the same direction as inFIG. 4.

[0041] As a result, the oval holes H formed on the side of the tubularbody 54 are exposed to the outside of the hollow housing 52, namely, tothe interior of the cosmetic powder retaining tank 30. In the statewhere the top end of the tubular body 54 of the adjusting part 50 hasbeen in contact with the horizontal body 56 b, the opened top end of thetubular body 54 and the opened end on the bottom end of the injectionnozzle 40 are communicated with each other, thereby flowing air therein.At this time, between the top end of the tubular body 54 and thehorizontal member 56 b is provided a rubber packing material 53 formaintaining their connection in a tightly closed state.

[0042] Referring to FIG. 5, in the state where the oval holes H on theside of the tubular body have been exposed to the interior of thecosmetic powder retaining tank 30, if a pumping switch of the airpumping part 32 is pressed toward the arrow direction, air flows to thecosmetic powder retaining tank 30 through an air discharging hole of thedischarging nozzle of the air pumping part 32. The air flowing into thecosmetic powder retaining tank 30 flows in the interior of the tubularbody 54 via the oval holes H on the side of the tubular body 54 and isthen discharged to the brush 22 through the injection holes of theinjection nozzle 40. Therefore, the cosmetic powder in the cosmeticpowder retaining tank 30 is finally injected to the brush 22 along theabove air flowing passage.

[0043] As a consequence, the brush 22 is uniformly covered with thecosmetic powder, without any irregular covering, such that the user canpaint the cosmetic powder on his or her face in the same manner as inthe conventional practice.

[0044] After the painting ends, if the cylindrical member 56 a of thepressure member 56 in the adjusting part 50 is raced in the oppositedirection thereto, the horizontal member 56 b screw-coupled on theinside of the cylindrical member 56 a moves in the opposite direction tothe arrow direction of FIG. 4 and in engagement therewith, the tubularbody 54 of the adjusting part 50 moves to the top end of the hollowhousing 52 by the elastic force of the elastic body 58. As a result, theoval holes H on the side of the tubular body 54 are kept in a closedstate by means of the hollow housing 52.

[0045] In this case, if the state where the brush mounting member 20 andthe adjusting part 50 are screw-coupled is released, the user can carrythe cosmetic brush assembly in a more convenient manner.

[0046] On the other hand, when the cosmetic powder in the cosmeticpowder retaining tank 30 is all consumed, the hollow housing 52 of theadjusting part 50 is separated and new cosmetic powder is filled in thecosmetic powder retaining tank 30. Next, the hollow housing 52 isre-assembled to the cosmetic powder retaining tank 30, such that thecosmetic brush assembly according to the present invention can besemi-permanently used.

[0047] Also, the opened top end of the cosmetic powder retaining tank 30is in a closed state by means of the adjusting part 50 and the ovalholes H on the side of the tubular body are kept in the closed state bymeans of the elastic force of the elastic body 58, thereby preventingthe cosmetic powder in the cosmetic powder retaining tank 30 fromleaking to the outside, such that the cosmetic brush assembly accordingto the present invention can be kept in a clean state.

[0048] On the other hand, FIGS. 6 and 7 show the cosmetic brush assemblyaccording to another embodiment of the present invention, in which thesimilar reference numbers to those indicated in FIGS. 1 to 5 areindicated with a prime. Also, an explanation on the same parts in theone embodiment of the present invention will be avoided for the brevityof the description.

[0049] Referring to FIG. 6, first, the adjusting part 50′, which ismounted between the brush mounting member 20′ and the cosmetic powderretaining tank 30, includes the hollow housing 52′ and the tubular body54. The hollow housing 52′ is screw-coupled to the cosmetic powderretaining tank 30 and fitted to the brush mounting member 20′. In otherwords, the brush mounting member 20′ is provided with reentrant grooveson the outside of the bottom end thereof, and in correspondence with thereentrant grooves, the hollow housing 52′ is provided with protrusionson the inside of the top end thereof. And, the tubular body 54 iselastically supported and inserted into the hollow portion of the hollowhousing 52′. Therefore, in the state where the tubular body 54 issupported by means of an elastic body 58, the top end of the cosmeticpowder retaining tank 30 is kept in the closed state by means of theadjusting part 50′.

[0050] Thereafter, as shown in FIG. 7, the brush mounting member 20′ isfitted to the top end of the hollow housing 52′ of the adjusting part50′. At this time, the injection nozzle 40′, which is inserted into thehollow portion of the brush mounting member 20′, applies a force to thetop end of the tubular body 54. As a consequence, the holes H formed onthe side of the bottom end of the tubular body 54 are exposed to theinterior of the cosmetic powder retaining tank 30.

[0051] Under this state, if the air pumping part 32 mounted on thebottom end of the cosmetic powder retaining tank 30 is manipulated, theair flowing to the cosmetic powder retaining tank 30 moves along the airflowing passage in the interior of the cosmetic brush assembly, therebydelivering the cosmetic powder to the brush, as discussed above.

[0052] On the other hand, referring to FIG. 6, a substantiallycylindrical flange is attached on the bottom end of the injection nozzle40′ inserted into the hollow portion of the brush mounting member 20.Also, a rubber packing material is disposed between the cylindricalflange and the top end of the tubular body 54.

[0053] Hereinafter, referring to FIGS. 8 and 9, an explanation ofanother brush mounting member of the cosmetic brush assembly accordingto the present invention will be discussed. In this case, the cosmeticpowder retaining tank 30 and the adjusting part 50′ are discussed withreference to FIGS. 6 and 7.

[0054] Referring to FIG. 8, a brush mounting member 120 includes: ahollow housing 122 having a mounting part 122 a which is mounted on thecosmetic powder retaining tank 30 or the top end of the adjusting part50′ on the bottom portion thereof and a first hole on the center portionof the mounting part 122 a; a substantially cylindrical member 124inserted into the hollow portion of the hollow housing 122 and slidablein a length direction thereof; a brush support member 126 for mountingthe brush on the top end thereof, installed on the inside of thecylindrical member 124 and forming a second hole coaxial to the firsthole of the mounting housing 122 on the center portion thereof; and aninjection nozzle 128 positioned in the interior of the brush 22 on thetop end on which a plurality of injection holes are formed to passthrough the first and second holes and having a powder flowing enddisposed towards the cosmetic powder retaining tank 30.

[0055] On the other hand, the brush mounting member 120 according to thepresent invention further includes a cap 130 to which the mounting part122 a of the mounting housing 122 is assembled, for preventing thepowder flowing end of the injection nozzle 128 from being exposed to theoutside, in the state where the brush mounting member 120 is separatedfrom the cosmetic powder retaining tank 30 or the adjusting part 50.

[0056] Therefore, in the state where the brush 22 is exposed to theoutside of the mounting housing 122 and the cap 130 is removed out ofthe mounting part 122 a of the mounting housing 122, the mounting part122 a is screw-coupled or fitted to the cosmetic powder retaining tank30 or the top end of the adjusting part 50′. Next, the air pumping part32 is manipulated and thus, the cosmetic powder in the cosmetic powderretaining tank 30 is uniformly injected to the brush 22 via theinjection holes of the injection nozzle 128 along the air flowingpassage.

[0057] After the painting ends with the cosmetic brush assemblyaccording to the present invention, as shown in FIG. 9, the brushmounting member 120 is separated from the cosmetic powder retaining tank30 or the adjusting part 50′ and then, the cap 130 is covered on themounting part 122 a of the mounting housing 122. The cylindrical member124 is raised in the arrow direction and inserts the brush 22 in theinterior thereof. Next, a cover (which is not shown in the drawing) iscovered on the cylindrical member 124, thereby preventing the brush 22from being exposed to the outside.

[0058] Referring to FIGS. 10 to 13 b, on the other hand, the cosmeticbrush assembly according to yet another embodiment of the presentinvention is embodied in the same manner as in FIG. 1, except that afirst screw is formed on the outside surface of the top end of a tubularbody 154 passing through the hollow portion of a hollow housing 152 andthus slidably mounted thereon, a second screw coupled to the first screwis formed on the center of a horizontal member 156 b, a brush fixingmember 24 for fixing the end of a brush 22, the brush fixing memberbeing separable from a brush mounting member 20, and a cylindrical tube26 installed on the center of the lower end of the brush 22, forsmoothly moving the injection nozzle 40.

[0059] According to the cosmetic brush assembly of the yet anotherembodiment of the present invention, as shown in FIGS. 11 and 12, if acylindrical member 156 a rotates in a predetermined direction in thestate where the first screw on the top end of the tubular body 154 iscoupled to the second screw on the center of the horizontal member 156b, the horizontal member 156 b moves downwardly, with a consequence thatthe tubular body 154 of the injection nozzle 40 moves downwardly. As aresult, the oval holes H formed on the side of the tubular body 154 areopened to the interior of the cosmetic powder retaining tank 30, and inthis state, if the air pumping part 32 operates, the cosmetic powderretained in the cosmetic powder retaining tank 30 is injected to thebrush 22 along the flowing passage as mentioned above.

[0060] On the other hand, if the cylindrical member 156 a rotates in anopposite direction, the tubular body 154 moves upwardly and as a result,the oval holes H are closed by the hollow housing 152.

[0061] As described above, the first screw on the top end of the tubularbody 154 is coupled to the second screw on the center of the horizontalmember 1 56 b, such that the tubular body moves upwardly and downwardlyin engagement with the rotation of the cylindrical member 156 a. Hence,the cosmetic brush assembly of the yet another embodiment of the presentinvention does not require any elastic body for supporting the tubularbody 154.

[0062] As apparently shown in the foregoing, a cosmetic brush assemblyaccording to the present invention is capable of covering a brush with acosmetic brush by the air pumping operation of an air pumping part,thereby ensuring a high grade of cosmetic brush assembly and preventingthe cosmetic powder from leaking to the outside.

[0063] Additionally, a cosmetic brush assembly according to the presentinvention is capable of increasing an injection force of the cosmeticpowder injected from a cosmetic powder retaining tank, thereby achievinga uniform dispersion of the cosmetic brush to the brush and adjusting anamount of cosmetic powder injected, thereby achieving a satisfiedpainting.

[0064] While the present invention has been described with reference toa preferred embodiment, the description is illustrative of the inventionand is not to be construed as limiting the invention.
